Your second link gives me an error:

Now amended.

The first link doesn't appear to me to justify the statement that "of course not all libertarianism is 'contra causal'". The Wikipedia article makes reference to a class of libertarian theories that don't involve a non-physical mind overriding causality, but the only example of such a theory it says anything about is Kane's, and it's far from clear to me that Kane's notion of free will is really libertarian (for the reason given in the article and ascribed there to Randolph Clarke).

It's far from clear to me that the objection sticks for the reasons also given in the article. But just about everything is disputable in philosophy. So there is no clear cut fact that libertarianism is "contra causal".

I don't much like the term "contra-causal", though

Neither do I.
